Looking good. I can see some halos around the edges of the flowers. You may have to fix this in Photoshop. Sometimes there are bits like this that don't get stacked properly and you have to fix.
Keep at it! Remember you can practice on anything around the house.
Nice one. - a quick way of getting rid of halos is the use the healing brush in PS to copy bits from the original image back onto the stack - this should give you an idea on one way to focus stack by hand.
