First fix the link to your Flickr.
I could smooth it out on the Rhinoceros Beetle, but I like the effect
Time to start not liking the effect! It took a fair bit of criticism, and some time for me to realize that too. The effect of crumply paper looks terrible in photos. Especially of tissue-foil. It also really doesn't look good in person, and can even make you look like a poor folder. There are a few times when some wrinkles are appropriate, such as for elephants, rhinos, and old people, but most of the time, you really want to try to avoid them.
Tissue-foil is a trap. It's very easy to fold, but hard to fold well. And you'll want to avoid squeezing as much as you can. Try to use true folds. At the end if you're narrowing insect legs or something, the one final pinch can be okay, but do it the same as you would with regular paper. Mashing is bad.
Cleaner folding allows us to actually see your work. With T-foil, you can generally make something recognizable. But it's really hard to judge folding quality (usually appears pretty bad), lines and form, etc.
