What do you think of my painting?

It's pretty cool... i'd like that for my room... i guess it just depend on how his living room looks like...

I think you need to plan your work before you start. If you'd drawn out the lines first your piece would look sharper and more pleasing, I know planning is tedious but it really does work wonders for the quality of your finished work. When you're creating a piece like this with a complex pattern, it's best to figure out exactly where each line goes, how and where it curves and how best to transform from one colour to the next, again tedious I know but it'd really help.

Also, working on a black background might've made the colours pop a little more, especially if you'd given some of the curves a touch of a highlight. Actually, multiple layers of colour would make it stronger and give more depth too.

I think it looks cool
