It works!

Nice shot

EDIT 1:

Just as a "pro tip":

The OEP is stored in EDX after these loops:

00401350 |> /AD        /LODS DWORD PTR DS:[ESI]
00401351 |. |2BD0    |SUB EDX,EAX
00401353 |.^\E2 FB    \LOOPD SHORT FastPack.00401350
00401355 |. 8B03    MOV EAX,DWORD PTR DS:[EBX]
00401357 |> 3B03    /CMP EAX,DWORD PTR DS:[EBX]
00401359 |.^74 FC    \JE SHORT FastPack.00401357
