You could say it's a mash-up of all of those. For this piece I didn't do any 3D renders as I needed to work fast. So this is mostly made from alot of different pictures of different types of transformers e.g. Optimus, Megatron, starscream and ironhide. The parts were masked, extracted, painted with stamp tool, all which I felt would best achieve my goal in each specific situation. I've basically mashed alot of interesting parts into shapes following a skeleton which I painted. I research the type of hand and which structure to use beforehand. To further merge the image together, I painted dark grey/black colour onto a overlay layer to give it the correct shading and for the overall feel of colour I used a colour balance layer. The LP logo is standard photoshop lighting techniques with some layer effects added to it. I left the title rather small as I wanted to give room for the artwork without the text taking over the image but it all comes down to preference I guess. Hope this will suffice.
