My pleasure - haircuts really give a great sense of confidence, especially when they look really sharp and are freshly cut.
As far as keeping the hair like that I would recommend trying American Crew Fiber or the foaming molding cream. They will keep the shine on the hair low, and provide a solid amount of hold. I have used a million products and always come back to Fiber, then just lock it in(I prefer my hair more firm) with a little bit of hairspray which can be anything you like or whatever fits the budget. Fiber is AWESOME stuff when combined with just a bit of hairspray(at least for me as my hair wants to fly away sometimes). You may also like Hans de Fuko Sponge Wax if you can find it locally.

I really like this hairstyle alot, been wearing it or a modified version of it for years, a lot of compliments, easy to maintain and style(like 2-3 minutes at most) and very very versatile.
As far as "harder" lines - by this I just mean that longer flowing hair create softer, rounder lines that make everything look softer. Spikes and straight short hair is more crisp. Flowy curly hair gives a soft look.
Also, I don't know how far you want to take it, but if you want your hair a bit straigher, you can blow dry it on low(should be only a minute or 2) and then apply your product - work a pea sized amount into your finger tips and distribute throughout the hair, then repeat with more if needed. Less really is more, I do my hair daily and only buy a new Fiber container everything few months.
I am big into men style and fashion, big on human physiology(my formal education) and the art of body maintenance and staying youthful in body and mind, big on strength and conditioning, bodybuilding, anything that would be a "male" topic including helping guys with their "game" with the opposite sex, small business topic anything related to success. To be frank and honest, I just love life and helping/sharing.
