Accuracy is the key to getting the points right. If you take the time to cut accurately and take the time to fix anything that isn't straight and accurate then you will get good points. this is not a place to say oh well it's good enough. Biggest thing is to make sure you have a 1/4" seam allowance left between where your seams meet and the edge of your fabric when you join hsts.
When I see a quilt block that doesn't have enough seam allowance left on the edges you know the points will be lost when it is sewn to another quilt block. This usually is a quick fix if you just tighten your seams.
