I took one of the most recent sketches and pushed it forward and now it looks much easier to read. Lots of reference from Celtic and nature ornaments is really helping a lot. I'm sure design needs more tweaking, but I can feel that it becomes much stronger every time as I represent a different version.
I also tried to record some of my stuff, because it is always nice to watch your own quick process and try to find short-cuts, so that next time you could draw similar thing much quicker or better, but this time I messed up. The video is not focused on the drawing and I also had resolution problems which dropped down the quality a lot, but next time I should remember to check my settings before recording.
