this really reminds me of the rose in beauty & the beast.. and the realism in the petals is great, you really should be commended for that so.. yey for you! good job! i can really appreciate this peice because i like to draw roses & im currently having to make them out of paper for a class.. and so i know how thoroughly FRUSTRATING it can be.. so kudos to you.
i think the green and yellow and black all works together really well.. and it looks so soft..
the fact that the rose appears to be glowing is a nice touch.. it plays off of the sunburst at the top, making it appear even brighter than it is.
youve got all sorts of linear directional forces going on, it would surprise me a great deal if you have not taken a design class.
constructive criticism: i must nitpick because there is not anything obvious or anything really that 'needs' to be improved.. but if the shading was more dramatic, that i think could help it be even stronger.
overall: uber kawaii! fantastic!
im very impressed.. and i must go see your gallery!
thanks alot for your great comments , it show a realy great care , you are such agreat person , oh ya , i didn't took any classes to be honest ,i took one class once and the teacher told me after 10 min to forget to be an artist
and yes , the shadows are an important part of the artwork , hopfully i will be good at that with time
