In some sigs, just forget the text because it can do more harm than good.
I think this isn't one of your best ones,
It's a smart concept, with a bright idea but I think the execution wasn't done very well.
The clouds are nicely placed, text not so good.
I think it's too simple, it could be the size.
Try some bubble sigs and some smudging and try a few filters and colour tampers and see what difference it makes.
P.S I can't comment many more cause i'm in germany and I check the computer once or twice a week.
