Thanks for making a gallery.
I like everything...that is not bad for only two weeks! I can't do some of your stuff you did.
I suggest you make a signature with a render, and see how it comes out.
Good to see some new wok here. Welcome to the forum!
I like your current signature, and I also like the last image. I am not really crazy for the 3D one though. But, good start to your gallery!
