I'm not really into facial hair, but I could DEAL with yours if I had to. I'd say nah, but that's just me. Some girls are into it and others are not. :) For your face though it doesn't look that bad. You could probably work it if you dont go any longer.
As a guy who has had a beard for over 40 years, sometimes long and sometimes just stubble, I would say yes it suits you. At the current length it looks really good. Test it by seeing how you feel it looks when it gets longer, but it's easy to keep it trimmed short if it starts to irritate at about 2 weeks to 4 weeks. This is when some people go back to shaving. I think its when the hairs get longer and tangle so just run a comb through it if it starts to irritate. Some guys can't grow an even beard. Interested to see what the girls think.
