About the designs, I like the colored squares at the top of the light bulb. The bulb itself is a very used symbol that has become a "cliché". Try not to go with what people like or you will be just pleasing everyone but yourself ;) I think it is healthy to know what people like, but not let it define your style. Or maybe yes, why not? Listen to yourself.

The letters can become a very nice pattern or texture if you choose the right colors (markers are hard to work with because they are very saturated and dark-colored.

Something that needs to be worked at are the concepts. This is the hardest and trickiest part. Abstraction, improvisation, caos and just plain mess play part of my work most of the time, though. Others, I do work on making conceptual artwork.

I really like the idea of just being able to put out there whatever comes to my head. This way I don't feel limited and just keep the ball rolling.

I'm new here and at the very base of experimentation with all this. Hope we can connect and share what we learn.
