Professional graphic designer here: #4 is the best, #3 could be the best if it was tweaked. Short reviews: #1 Colors are off The design has no visual flow Spacing is off THe arrow image is generic and poor quality #2 Text is nice but the image on the left breaks it Lacks visual flow ( I don't read is as "PC Pedia" but like "Pedia" and asume the PC is just the company image) #3 VERY nice design. Good use of color and contrast Same problem as above, the "PC" is below "Pedia" and doesn't read as PCpedia #4 Definitely the most professional Logo is a little generic (which is fine for tech stuff anyway) Use of fonts/colors is top notch
