Becoming a graphic designer

So, I have a little opportunity to get some free advertising, all I need to supply is an A4 poster for my company. Yesterday I sat down with photoshop and came up with this. Anyways, as I am not a graphic designer and am just relearning photoshop after 14 years, I was pretty happy with the result. Having the lighter box behind the word wax was a bit of a happy accident, I had it as white text, but when I selected the word, it showed it as black with a lighter background, and it looked great, so that's what I did. Thanks photoshop!
