First design, second attempt, and more cars. Ice & Fire v2 - WIP - Any feedback is appreciated!

So I'm new to Forza and in the process of figuring how to make my own designs. I was having trouble finding ones I liked, and I always enjoy learning new things and trying to get good at them, so this was perfect for me.

This was my very first attempt at it a couple days ago for the Evo VIII MR 2004.

I know it's not an impressively original idea or anything, but I like it, and some others seem to as well. It feels so amazing getting that in-game mail telling you that people have used/liked your design! It was fun to make, and I learned quite a bit.

The Audi R8 V10 Plus that I originally linked is my second attempt. I ended up using more than twice as many layers and I think it shows. I managed to smooth it out a bit more, and figured out some techniques in the process that should have been obvious from the beginning.

Here's a second version of the R8 I made with actual flames and ice crystals per request. I wanted to keep it minimalist because I generally think flames on cars look tacky.

And here is the most recent one I've done for the BMW M4.

Technically they're all WIP. Any tips, advice, criticisms are more than welcome. If you like the design and want one made for a certain car, just let me know!

My GT is Jaxim Fenix for anyone who may to add me or check out my stuff.
