Resin has to be one of the most difficult mediums I've experimented with.
In my artwork above, I painted the raft first and then dirty poured the multi-colored resin on top. This ended up covering the raft so I had to repaint it after the resin cured and then pouring another layer of resin. But in the end it turned our pretty good.
There's a lot of texture and movement that was created because of the layers so the extra effort was worth it.
Let me know what you think :D
