Thanks for your feedback, Kate  I have applied your advice to my third Apple can you see the difference?  Will be sending the petals! Thanks Following Kate’s session on ‘painting for the terrified!’, I had three attempts at painting my apples at home. Colours used in 2 and 3 were cadmium red with alizarin, Winsor Yellow with raw Sienna, cobalt blue plus raw umber (Daler Rowney) with French Ultramarine blue for the centre and stalk. 
thinking two and three looked a bit like tomatoes I used Aquatone watercolour sticks to create texture and mottled colour. Having passed through the stages of tomato and nectarine , they came more to ressembling apples I think!? 

thanks Kate!
