Don't be sorry! Looks awesome dude, apart from what others have pointed out, this might not tile the best. Looks like you took the effort and hand painted some stuff in as well, instead of solely relying on your sculpt which is ace.
This will not tile well. Because of this dark spot on diffyse. You can try expanding the canvas size and copy the layer with diffuse 4 times and place it on the canvas. Then You will see how it tile and where it's very repetitive. Or just try to tile the diffuse on every engine or 3d app. for me colors and normals are…
