I was curious to see how I could improve it with my knowledge of image editing, so I saved the image files for each feature of the dragons, upscaled them about 4x, and by now am almost finished making a couple of tweaks just to neaten them up. Eventually, I'd like to see the dragon generator recreated as a software that would integrate the image files as layers where you'd be able to change their brightness/hue/saturation values, instead of having extra layers for different color variants of the same thing. I even have a concept for how the user interface would look like in the works.
The coding aspect of it is still beyond my expertise, and although I wouldn't mind seeing how I fare with the challenge on my own, I can see it getting done quicker with a volunteer on board, if anyone's interested.
Here's some samples to show how I've enhanced the customization so far:
I'm just gonna stick to the Krome Studios style for this, since I'm honestly not a big fan of the pseudo-3D render look of the DotD style dragons.
