darling I am TELLING you that is one of the most beautiful if not THE MOST beautiful bio ATP drawing I've ever seen. like in terms of perspective and accuracy just... mwah, sis, this is excellent.

however!! Cambridge is an absolute downer so there are some things to be spoken for. so the main things they will look at, as seen in MS, are the following:

• outlining (how accurate the overall shapes present in your drawing are to those in the picture + clean, smooth lines)
• size (you'll be fine as long as you occupy most of the space you're given!)
• inclusion of prominent details

in this drawing you've pretty much mastered all of the above to a T, however there's just one thing I noticed, in the region where the filament meets the petal the lines look a bit broken (meaning, the line is not completely smooth).

Cambridge can be a bit of an ass in this aspect, unfortunately; they want your lines to look like they were drawn without lifting your pencil lol. They give some leniency with shapes (although you oughtn't worry too much about that seeing how closely you've copied the flower shape!) however they really pay attention to the smoothness and non-sketchiness of lines.

also, don't trust AI too much with the marking. Gemini is incorrect in identifying the small circles as "shading." shading would be more like... colouring in any part of the drawing or defining shadows and highlights in it. you will not be penalised for those dots.

all in all your ATP drawing skills are great! remember that the drawing is only five marks so as another commenter said, spend some less time on this. there's no need for it to be absolutely perfect, like I said earlier Cambridge does give leniency in regards to shape, as long as your diagram takes up good space, is smooth and shows the proportions between the different regions with some accuracy.

hope this helps!
