I figured a tip/trick for myself. When I'm done sketching I take photo and analyze my end result if the proportions were right. I noticed there was too much negative space between the letters 'A' and 'N'. As you can see the faded version of the piece was slight off. The dark version is the corrected version. I was able to fix it and compare by overlapping both sketches to see the difference. Worked like a charm and I happy with the result!!
