I personally aren't too fussed on looks which many people find surprising but I just like a guy to be comfortable in himself and have confidence in his looks however in answer to your question:
I like medium sized lips on a guy, not too thin but then not too big either. I like slender built guys and I like them to have a sort of scene sort of style. Piercings suit different people, most guys I like have piercings, especially either snake bites and ear piercings. Brown eyes aren't boring! I think darker eyes suit people with darker hair and blue eyes suit people with lighter hair. I like medium hair (sort of to the length of your cheek bones) and I like a side fringe too.
..At first Personality...I mean if we can't "connect" why should I care about his eyes/ hair etc?But if he has everything that I want in his personality -sense of humour, open hearted, self confidence etc- then if I had to pick appearance traits I would like him to have brown hair and brown eyes- he gets a plus if he has gray eyes, they re soo rare that's why I like 'em...And medium length hair...And I hate piercings on a guy...As a style I like rock style...
Brown eyes aren't boring at all! I have brown eyes, after all. I find them nice
As for piercings, they're usually pretty hit or miss for me. Lip piercings can be incredibly sexy, but I hate eyebrow piercings, for example. I usually think ear piercings on a guy are pretty cute.
As for lips and hair... I can't give you a specific answer for that, since it varies from guy to guy. If you had some different hairstyles in mind, maybe you could link to pictures of them so everyone can get a good idea of what they look like and give you feedback that way. Or just post a picture of yourself?
