The patterns on there tummies is not always due to stress , if he's basking, eating, exploring and calm when interacting with your he's likely no longer suffering relocation stress.
Comments :
I'd loose the hammock - serious nail snagging risk ==> high risk of him injuring his arms or legs in an effort to unsnag him self.
I'd also ditch the analog thermometer attached to the back wall ,they are worthlessly inaccurate.
The 100W Megaray MVB is too far away from the basking spot ==> UVA & UVB will be quite low at the basking spot and even lower elsewhere.
From the site
http://www.megaray.co.uk/mega-ray-100w-mercury-vapour-bulb-self-ballasted-p-145.html
MINIMUM distance setting of 12" will produce approximately 150-200 microwatts per square centimetre (uW/cm2) of UVB and 900-1200uW/cm2 of UVA.
MAXIMUM distance setting of 16" will produce 50-75 microwatts per square centimetre (uW/cm2) of UVB.
(Distance is measured from lamp face to basking spot or reptile for optimum UVB and heat.)
I'd endeavor to set up the basking spot so it's NO FURTHER THAN 12 inches from the bottom face of the Megaray MVB AND remove any mesh in the lid where the MVB is sitting, as the mesh will block 40% of the UVA and UVB.

The issue with all in one MVBs is the beam of UVA & UVB is very focused and confined in a small area , this is fine in very small footprint vivs , but not so flash in larger footprint vivs , even small viv like your's. I recommend adding a 24W T5HO 10 - 12% UVB tube in a reflector hood mounted UNDER the mesh lid to provide UVA & UVB over most of the viv , should be not more than 3/4 the length of viv and have one end adjacent to the basking globe/ MVB.
I also recommend lights on a timer on a 14-16 hour schedule ( on 6am , off 10pm say ).
I also recommend investing in some of these :

I have 3 per rearing tub / tank and can see my temperatures in these at a glance.
