I have spent ages looking at this and it seems to me that the main light is coming from the left. I am wondering if it might have been better to have had the half strawberry on the RHS as the moisture on the cut surface may then have been more evident, always supposing it was freshly cut. I have done a couple of fruity images since this challenge and it is surprising how quickly it dries out.
Having said that, you have made the fruit look very appetising, with lovely detail and colours and overall the shot works well.
I am very nervous about giving critique, particularly on the technicalities and like you I am hoping that it will get easier.
