Considering that D&D, Warhammer, Warcraft and others do indeed feature weird contraptions and strokes of technical genius, I don't see why steampunk-y elements should be a problem. Have your zeppelins, or the odd gunpowder weapon, that's perfectly fine. Dwarfen or gnomish creativity is a rather common element in a lot of fantasy franchises - just make sure you don't throw in lightsabers or laspistols in there, and put in some details as to how they're not all that common or why they're special.
Steam Tanks are monstrous, smoke-belching creations that rumble towards the enemy, firing deadly cannon balls from their steam-powered guns. The advance of these iron behemoths is terrifying to behold, as arrows ricochet from armoured hulls and enemy warriors are crushed beneath their immense bulk.
The Warp Lightning Cannon is a weapon of pure destruction. Created by the Warlock Engineers of Clan Skryre, it has the power to tear apart units and monsters with ease. While Clan Skryre perfects the art of firing incandescent balls of warp lightning, the Plague Monks of Clan Pestilens are busy launching toxic sludge from their Plagueclaw Catapults, which brings long-range death to the arsenal of the combat-oriented Plague Monks. Armour offers no protection to those hit by the deadly payload of the Plagueclaw catapult as it will eat through metal, skin and bone without discrimination.
As long as they make sense in the context of the world and characters, and have some nice descriptions and/or explanations mixed in, there is nothing wrong with having such stuff. The above examples have been well-established in their worlds, but are more like mad strokes of genius or highly rare and unstable experiments. Gunpowder weapons exist for sure, but aren't as widespread as bows, crossbows or the likes. People know they exist, but unless they're either very lucky, wealthy or elite troops in an army, they'll hardly gain access to these things.
The thing I'm getting at is: Don't let technology undermine your story, and make sure they're well-considered. Also make sure they make sense in the hands of the user. Try looking at fantasy tropes, for example.
But yeah, I won't rule those steampunky elements out. They're interesting after all!
That's the way I've experienced you in those projects, yeah. Eager for some ways to test yourself and improve your stuff. And you're right, absolutely, I intend these projects to be learning experiences, first and foremost. That's why I want people to leave comments and feedback on the submissions, and try to push some less natural topics to get people out of their comfort zones.
I'm glad people are willing to give it a shot, even if the genre is something like Horror or Fantasy.
