You're a true Inkscape genius dude. Just ... wow! I'd like to learn how to do this type of stuff with Inkscape, but the best I can do right now is logos and some simple art without any "pro" shading or anything like that.
Do you have any advice on how I can learn to do this type of stuff? Any specific tutorials, resources or things like that? I mean, from my perspective, this is like ... impossible with Inkscape lol.
Haha.. thanks for the compliment! Regarding tutorials and stuff I'm afraid I can't help you much. I haven't really used many such resources and instead learned via the old trial&error method The manual and the mini tutorials in Inkscape's Help menu are a good place to start and get a grasp of all the basic tools. Beyond that? I guess just search for specific things you're interested in.
Good luck and have fun with Inkscape!
