Thank you! No need for flattery though, from what I can see on your profile you're already way better than me.
It's not vector, actually: it's all simple raster shapes in Photoshop, passed through a couple dozen layers and effects (especially visible on the logo there). I don't work with vector graphics, but I'm planning to pick it up sometime soon.
Not flattery at all! I have ideas, but I still have a lot to learn when it comes to vectors as I am very very new to them! I am OK with photoshop, but I have been using that for years! I thought this was a vector because the lines where so clean! (Though I suppose you could have used shapes. ) I have a hard time drawing clean, stright lines in Photoshop, (Probably cause I don't have a tablet.) So I am very happy to have discovered Inkscape! You should definitely give it a try if you haven't yet!!
But, I can't draw to save my life: everything here is an equivalent of making a rectangular selection and pressing "fill", something that I'm sure would make any good vector artist bang their head against the wall, while this one - [link] - would make them want to jump off a roof.
I think in any program where you can work with different layers and add and subtract shapes, you can do the same. I'll definitely give Inkspace a shot.
