These look pretty solid. I don't see any major issues that need addressing. You just need to get stronger. Everyone hits roadblocks at different points so don't be discouraged if 245 is hard for you. I know that for me personally 185, 225, 255, and 275 haunted me until I got stronger and moved passed those numbers. The numbers in between kinda of just came and went. Now 315 is my next arch nemesis.
