Really cool book you have here sir. Last one is particularly cool. Think you need to "fool around" more, if that's what it was - actually looks like there was a good deal of thought invested in it. See how those trees in the background the vertical strokes make the whole thing feel more tense? Makes it eerie. It wouldn't have had the same feel if it didn't have those vertical lines in it colliding with the horizon. Think all it need is for the signature to be in the same colour as the horns - just to balance it.
But thanks for stopping by my book - keep the good stuff coming!
PS Oh, and B&W is for sissies and bedwetters; Real Men use Real Colour!
