So, here it is!
As you can see, the marks show that the marine is an Assault marine of 2nd Company, 7th squad. I didn't put squad number on the bike, even thought it should be there according to Insignium Astartes. It seems illogical to me that the bike should show squad number, but not a company marking, so I didn't paint the squad number at all. After all, according to the fluff, bikes belong to the chapter Armoury, and not to Companies (as do Rhinos and some other vehicles); the Companies instead request them according to mission requirements.
This picture shows a better detail of the base. I modelled the base according to a tutorial that was available on the Games Workshop site, but it looks like they took it down now! The base is covered by a thin layer of Green Stuff - and the bike track was made by pressing a spare Bike wheel into it. The effect is pretty cool, and complements my idea of a swamp planet pretty well, although most of the track is covered by the bike anyways. Here is a detail shot of the base, before I put the bike on it:
Regarding the bike model itself, it can be seen that it's mould dates back to the third edition. The detailing is simply not that good, but luckily a good paintjob can cover that well! I hope I have achieved that.
And that's about all for now, so - thanks for reading! As always, comments are most welcome. After all, I still have five more of these to do, and an assault bike as well!
