Tinder is kind of s**t, so that means nothing.
That being said: shave and get a haircut; the goatee slopes in a way that makes your chin look weaker, and that long fringe makes your hair look untidy.
Upgrade the wardrobe. No need to get fancy, but I suggest a solid-colour button-up instead of a print t-shirt. Avoid slim-fit if you're carrying a few extra pounds.
Practice facial expressions. I know from experience that we aspies often have that sligthly vacant/confused/sleepy/sad face as a default expression, and it's not generally considered attractive. My trying to do away with that has sort of left me with resting murderface, but that's still an improvement. Try focusing on something off-screen when you're taking photos.
oh, and heed ltcvnzl's advice about the photos.
