Hello, I appreciate that you made a texturepack for my datapack !
However, the textures could be a lot better. You won't learn pixelart in one comment, but here are 4 advices that can only help you improve:

- first, think about colors and volume. Try to create a limited palette, with colors that blend nice together, with dark and light colors for shadows and reflections (one thing to keep in mind is color theory ). When you put shadows and reflections, think about the shape and volume of your object; for example your etherium rifle looks flat because you don't think about what it should look like in 3d, how light would bounce on it.

- second, if you have difficulties with the first point, don't hesitate to take references ! See how a real gun looks, how is it made, so then you can imagine your own guns without making them look too thin or blocky. You can also look at the new minecraft textures, they are made by a professionnal pixel-artist and can only give you good starting base !

- third, very specific but avoid transparent pixels in minecraft textures when you can. It will mess up your item model. Not good.

- fourth and last, put more care in your presentation. Take pictures at day ingame so we can see your textures, and with a clear background so we only focus on the textures.

Annnd that's it. On the other hand, you've had many interesting ideas ! I really like the idea of a freezing gaz, and a kind of needle gun to heal is a cool idea ^^

Anyway, hope these advices helped. Have a good day !

Thanks for the mod, the textures look really nice! :>
