geschmackssache | PAT ATC reject

This is another of the cards I made as a potential ATC for a PAT "elephants" theme. I am still having a bit of trouble with my glue. I'm sort of perplexed. I'm using the same glue and gluing method that I used before, but it's not causing the paper to be all wrinkly/bubbly. I guess I'll have to experiment with some different glues here soon. Anyway, the gluing problem isn't so tragic on this card. Actually, it sort of enhances it-makes it look like wrinkly elephant skin! Watercolor, graphite, marker.
