Nice set of roses.You did your best, nothing to criticize in your work. But something red is very hard to get well. You get it in focus, but the red is trying to say no. The tones you have in your roses are there, but the red does not help you a little. Is difficult to get various tones in a red, all looks like only one.
Please understand I´m not saying nothing against your job. You did a wonderful job in difficult subject.
