The top right in your V1 seems to busy. I personally like V2 better. A couple tweaks; ie. a couple more filters, etc. to both and they could be really good.
IMO, V1 is better. Don't like the vector type style of V2. Left side of V2 seems to just go from effects to smudging. Nothing to really bridge one from another. Like the lighting in V1. Keep it up.
V1 all the way, V2 look to worn out, if that makes sense. Nice Job, Keep It Up. Also i agree a little busy, but if your tag is busy with good flow and effect its good like yours. So I personally think its fine.
Not really but okay. The colors are good. The green and yellow feel makes it work well. The cut lines on version 2 make the sig have some originality. v1 could have a slight less chaotic right side, then the BG would be really nice.
