Looking for Advice on Child-sizing Bust

I purchased GCH a little while ago and it's amazing with editing and personalizing faces and sprites... But I'm having some trouble with figuring out how to make the face of the character smaller, to look like a younger child (age 12ish). I have discovered resizing in GCH, but I can't get the proportions right to look natural and not horrifying.



This is the character I'd really like to look younger. He's the White Rabbit in my Wonderland-themed game and he's a little kid. The blonde things behind his head are his rabbit ears. 

Does anyone have any advice or knowledge with customizing a bust in this way? Thank you so much!!

You should look into getting GIMP to further edit face sets. I personally use Photoshop but the transform tool can easily allow you to reproportion and place the features on the face set exactly how you like. When using the generator I heavily, note, heavily edit each feature of the face.

To make my face sets look younger I tend to make the eyes, proportionately, the biggest feature. Eyebrows will be more rounded. I tend to paint on rosy cheeks and freckles to a number of my face sets. These would be easy to do in Photoshop or another (free) equivalent.

Thanks for the quick and informative response! I use Paint.Net in lieu of GIMP and Photoshop. I'll give it a try on there and if it's not working out well, I'll try it with GIMP instead! 

I'm not sure if you're just looking for advice, or an edit as well, but here you go:

 
I have never tried Character Game Hub so I can't help you there
but if you need help with how to achieve that in an image editor, i'll post a short tutorial here.

You will need Paint.NET (or gimp, or photoshop), a mouse, and a face graphic. To minimize drawing, pick facial features that are childlike. Be ready to Undo (Ctrl+Z).

Dragging body parts into place
Visualize how you want the child's face to look, or use a reference image. Determine how the current image is different from the one you have in mind.
 
For each body part or section that you want to edit/move:

• Lasso Select to select it. (Edit>Cut and Edit>Paste into New Layer if needed.)
• Move or transform the parts using the Move Selected Pixels tool.
• (Remember that you can arrange the order of your layers to make some parts appear on top or below others.)

What I did:

• Selected the entire top section of the face, and moved it downwards.
• Selected the nose and moved it upwards.
• Selected the neck and shoulders, clothes included, and shrunk it horizontally.

Drawing over and correcting details
Now you probably have some empty spaces and awkward bits in your picture. We will fix that.

• (If you used layers: Once you are generally happy with the placement of the body parts, use the Merge Layer Down icon in the Layer window to reduce your work to a single layer.)
• Use the Color Picker and Brush tool to fill in gaps and make corrections.
• Use the Eraser to remove unwanted things around the edges.

What I did:

• Filled in the gap under his nose (Brush width: 3) and drew in his shoulders (Brush width: 3 for green, Brush width 1 for black outline)
• Erased some excess hair (Eraser width: 3, hardness: 100%) then drew some back.
• Corrected some jagged spots on his face that occurred when i was moving parts around.

 

Filling non-opaque areas
Your image looks satisfactory right now, but that might not be the case when you give it different backgrounds. How to test for bad spots:

• In the Layers window, Add New layer and arrange it under the face.
• Using the Paint Bucket (Sampling must be set to Layer! This is the default setting.), fill the background with any colour you chose.
• Go to Adjustments>Hue/Saturation to test different background colours. If you don't see anything strange, you're good to go. Delete the colour background, save, and you're done. 

Every face is a little different. Feel free to pm me if you get stuck.

Wow!! That is the cutest!!! Thank you so much! I was fiddling with GIMP and Paint.net, but I wasn't confident with the results...

Thanks theadellie!!
