Yes colour is not the best but I think you need to get the grammar sorted first to look more professional.
I thought the colors were attractive. I thought it was easy to see what you were offering. I thought you used the space well.
I think the very top and bottom parts look good. The middle shouldn't be all blue imo. Try using some different colors in the middle section so it doesn't all run together.
I dont know if you fixed it before, but now it's ok to me. However, you need improve it more, best luck !
