Firstly, I must say how great I think Inkscape is. From the high quality of work that I have seen in this forum so far, it seem to be a very capable program.
Anyway, here's my first thing I ever made in Inkscape, yesterday. It was a pretty steep learning curve for me, before I started it I didn't even know how to add nodes, but I am pretty impressed with what I have managed to make so far.

In case you can't see what it is meant to be, it is supposed to be a person reaching through some prison bars.
Please be truthful in replying, and tell me how you think I could improve this piece, like, shapes, colours, etc.
