Making a custom pose/ item is basically trial and error, just try playing around with bits in heromachine 3 until you come up with something you like. You won’t need a premium account to do that (although any support for Jeff would be appreciated). There is also a section on the Select Forum drop down menu at the top of the page that says Heromachine 3 Custom Items Archive which is full of custom poses and items other ‘Machiners have made, which you can use in Heromachine 3 by copying the text in the spoilers after the image of the item/ pose and then pasting said text into the Load From Text option on the load screen of Heromachine 3. Hope this helps.
Also, as moderator, I would strongly advise against posting Heromachine versions of Mortal Combat characters on the forums, unless they are your own Original Characters, because we do not allow copyrighted characters due to problems the site has had previously with copyright claims.
