problem analysis -Adding the pigeon silhouettes to my drawings.

though out the drawing and collage process of my illustration, i was conscious of the fact that a problem i would come across would be trying to accurately place the positions of the pigeon silhouettes onto of the collage material due to the texture i would have to work on top of, also i felt it would be difficult to concentrate on producing a clear silhouette line in amongst a busy background.
i decided it would be easier, and it would give a crisper outline, if i added the pigeon silhouette on photoshop. however, the problem of not having a accurate outline sketch of a pigeon to work from was still a problem.
i remembered from our photoshop workshop, that i could copy and paste textures on-top of a image- so i experimented with this and used the lasso tool to cut round the existing shape the pigeons from my photo reference material and then inserted them onto my illustration, this will provide a outline for me to draw round which i can later remove, leaving just the silhouette I've drawn ontop.
