I am no expert, I will only go by what I see when comparing your CAB SLB to mine.
First off I could not make out the box code on yours...can you post it?
Now mine is FIM MAR05 so the differences could be due to year changes or factory changes but on my box the word "CABINET" is in Caps, yours is on lower case, and the boarder around the "Jose Gener" in yours looks smeared or that the ink bleed out into the wood. My boarder is very sharp and clear.
From what I can see of the Warranty seal looks in the correct position and of the correct shade, you may want to take a better image of the seal. Do you have a black light....if so use it on the seal and you should be able to see a Lemon-yellow UV image of the "Coat of Arms"
The cigars them selves look a bit edgy with some shade difference in the wrappers But the bands look good to me. HdM uses a band that is embossed so you should feel the ridges on the band, it is a very nice band. Have you smoked any of these yet....it should help you decide if they are real.
If you bought these from a reliable vendor, maybe one posted at this site then from experience I would say that they are real, cuba does not always produce the best looking stock day in and day out on some brands, maybe you have a box from a roller that had a hard day!
You can take a look and compare yourself to my CAB SLB and the sticks in the images that I took when I received mine if you follow this link.

Hope that helps...let me know if you have any other questions, and maybe some other members that have more experience than myself will chime in on this one.
