Sus 4:
Basic structure is there, missing some finer detail. Textures, lighting 
and environment all need extensive work.

JPEGs:
I realize that I'll be preaching to the chior here to a fair extent, but 
there may be some new singers who haven't heard this before.

Most regulars here will have noticed that this kind of image (strong red 
diagonals on significantly differently colored background) usually looks 
awful when presented as a JPEG, or is a very large file to avoid the red 
jaggies. This can be easily avoided if you have a good tool for creating 
your JPEGs (I use the GIMP, there are many others). In the GIMP you do 
the usual steps like setting it to use a floating point DCT and 
optimizing the compression, then there is a setting often overlooked 
"Subsampling", this setting has a huge impact on the red jaggies 
problem. The default 2x2 discards 3/4 of the spacial color information 
in the subsampling step, the second option 2x1 discards half the 
information, and the final option 1x1 discards no information in the 
subsampling step. Obviously the less information you discard in the 
subsampling step the bigger your file will be, however for this image I 
found that balancing that change by moving the overall quality slider to 
bring the image to the same size for each of the three settings 
demonstrated that the 1x1 setting gave the best overall quality:file 
size ratio.

The moral of the story: never just click 'OK' when saving as JPEG, 
always tweak it to suit the particular image.

The small cutouts attached come from JPEGs of around 28k each, using 
each of the subsampling methods. The final is the same cutout from the 
original PNG.
