'Happy Birthday' Masculine Card

Making 'masculine' cards is such a challenge for me.  I tend to make them 'girly', even when I don't try!  I decided to try making one that was simple, and am pretty happy with the result.

My goal in making this card was to stick to 2-3 colors, and to not embellish it a whole lot.  How did I do?  Does it look 'masculine' enough to give to a guy?

I think I'll keep working on it!
