Eh I dunno, needs some scuff brush marks on the textures to help give it detail and not look so flat, the stars could also maybe have a little wear on some them

The main texture is really really bad , u need to change those sticker textures because they don't fit in tf2 at all

I will cut slack since it is your first skin but its just... bland. Sticker paints aren't that great and with them all being the same it makes it feel dry. Personally colors don't fly well with me but I don't like light colors and pink.

I don't know about this one. The main texture, from what I can see, is made up from copy and pasted stars on a flat background. The other flat colors do not help out with this issue. All around a bit boring and feels unfinished.

However, given that this is your first warpaint, it's a decent start to something that could be a lot better than it currently is.

If you want my advice, consider drawing multiple unique stars by hand and then placing them on a background that is shaded and colored like a late sunset, that would include using less saturated colors than bright salmon-pink. You can then change the flat black into a dim star-field. Finally, for the yellow, I'd recommend adding lunar craters.

Either way, for a first warpaint, it's okay. However, it has a lot of potential if you decide to hammer away at it.
