This turned out great for a first attempt.. The 1/2 square triangle on the right side is off..the seam is probably too deep. you made sure the edge point is there but the intersection where the bright colors meet is off..take the bottom section off to the center of the block and re-adjust the seam to the outside edge, when looking at the block you can see where the bottom row pulls up..the seam is too big there..If it were me I would redo that 1/2 square triangle too..you can see the bright triangle is much smaller than the one on the opposite side...This is a practice block and trying to get it right is a good lesson now ..I hope you don't think I'm being too critical.. I want you to do well and these little things can be the difference between a good block and a great block...
