Have progressed more with the concept art since last time..
Here is the blockout in Maya;
which I printscreened and pasted into Phothsop to draw over and create the basic lines and colours for the princess tower;
Then took that into SAI and tried to give it the same feel as this picture;
and here is the result!;
Maya is extreeeeemely helpful for work on perspective and has really aided me for this part of the project so I'm going to continue using it :)
Am also getting the hang of SAI. To get the strange canvas-y effect I have been using the 'Paper' brush and while it takes awhile to get the shapes right it is quite effective by the end.
Next is the entrance hall..
