It was supposed to look like some kid of bolt but ended up looking like a droplet, and the yellow stripes do make it look like a watermelon. Plus it didn't scale down well in the end
Scaling... my old arch nemesis... lol.
Ya, a lot of times what looks good as a big image just doesn't quite work the same on a small scale... and sometimes vice-versa.
At any rate, I kinda get the idea you are going for.
It came out a lot better than my attempt at art for my "Cornucopia" card... I went for divine heavenly glow... and ended up with sickly and virulent looking... lol.
If you are willing to dabble in GIMP or photoshop, I find that adding transparancy and glow effects can often help get a bit more of an "energy bolt" look.
*puts on openEtG enthusiast hat*
Are you opposed to the possibility of having this ported to openEtG by the way? It could be a fun card to test out there.
