Alan, The yellow strip (the bigger of the two) just to the left of orange Methanol strip. Is that for H2-ICE? You don't have an arrow pointing "H2 ICE" towards the yellow strip. You appear to have arrows pointing to everything else. I think it would be a good idea to put an arrow there as well, assuming that is for H2 ICE. Otherwise, I don't know what the yellow strip is for.
Otherwise, Looks pretty good to me. Regards, Steven Vincent Johnson svjart.orionworks.com zazzle.com/orionworks
