Even When You're Not Here My Hands Still Hurt You

I originally sketched this a very long time ago and then completely forgot about it so I'm not entirely sure what the original idea behind it was. I do think though it was partially inspired by this piece of music: www.youtube.com/watch?v=VmburH… . And probably came to me on some horrible, long sleepless night. 

I was talking to a friend in my class at college and through the conversation I realised that the concept aspect of my work is probably the weakest. Is it art if there isn't a strong concept behind it? Can I basically just paint stuff I find pretty and that's art? Normally I have a vivid image in my head of what I want to create and then I work towards that, but I noticed that she (and this is also what we're taught to do at college) starts with a concept, with no idea of what the final piece will be, and through design and experimentation creates an outcome. Does the process matter as long as the outcome is good? I also don't want to waste my time making work that won't help me get into uni. But I also just want to paint for the hell of it. Arhgndakj Man my head's a mess today.

I think the point of that rant was that I am having an art crisis and I need to chill out and just let it be _{Pretty sure this happens fairly regularly}
As for the piece I decided to use palette knives for the background! Never done that before lmao. But seriously, I am very very happy with how this came out.
Done in Winton oil paints on paper

Sorry for rambling, thanks for looking!
