Dont worry every graphic designer can provide final picutre with transparent background. You mentioned there will be blue background on website + you prefer cover in blue colors. I can make blue version from my design but I need to know/see exact backround you will use on website to make good contrast with blue colors on cover...I hope you understand what I mean :-)
Because I thought before that you will be using this theme: http://themeforest.net/theme_previews/122898-the-developer-wp3-edition That´s why I have created cover in green colors, and background on this theme is dark gray so there would be no problem with contrast
